Application of the IWA ADM1 model to simulate anaerobic co-digestion of organic waste with waste activated sludge in mesophilic condition

摘要

Anaerobic digestion model no.I model of international water association was applied to a full scale anaerobic co-digestion process for the treatment of the organic fraction of municipal solid wastes along with activated Sludge wastes originating from a municipal wastewater treatment plant.This operation was carried Out in a digester of 2000 m(3)in volume.It is operates at an average hydraulic retention time of 26.9 days with an average organic loading rate of 1.01 kg TVS/m(3)day,at a temperature of 37 degrees C with an average gas production rate of 0.296 m(3)/m(3)day.The aim of the present study is to compare the results obtained from the simulation with the experimental Values.The Simulated results showed a good fit for pH, methane and carbon dioxide percentages,biogas volume,chemical oxygen demand,total volatile fatty acids,inorganic nitrogen and inorganic carbon.
